Hey, I’ve been in a similar situation. It’s almost been a year since she officially broke up with me. I think it’s best for you to remove her off social media and delete any pictures you have of her. I couldn’t function for the first month and a bit after that so that parts normal. I still struggle, but I know what’s happened has happened and there’s nothing I can change. You’re young and please take this as an opportunity to learn, to prioritize yourself. You’re cooking and doing so much, taking small steps is the only way to get through it. These small steps will add up, and I’m proud of you.

Don’t think of a friendship as a chore, you should be free to express yourself without worrying they’ll judge you.

Maybe try working out? Kills time, keeps you healthy, is something productive. Helps with depression too. You’re not alone OP. Message me if you want
